Patent GB-2236225-A (GB)
Title: Superhetorodyne circuit
Inventor: SEYMOUR COLIN JULIAN
IPC: H03D7/18
Filed: 1989-09-23
Abstract: A superheterodyne circuit comprises a first local oscillator (3) f1 applied to a split input signal (1) to give phase quadrature zero intermediate frequency (baseband) signals which then have applied to them a non-zero intermediate frequency (25) f2 also in phase quadrature (27) via a second local oscillator (25). A combination device (29) then combines by addition or subtraction the resultant signals to provide an output in which the majority of unwanted signals (eg image frequencies) cancel out. The circuit may be incorporated in a receiver or a transmitter. <IMAGE>

Patent GB-2257377-A (GB)
Title: Oil-spill recovery equipment
Inventor: SALTER STEPHEN HUGH
IPC: E02B15/06
Filed: 1992-07-09
Abstract: Spilt oil is recovered from the sea by towing an inflated boom 1 - 5 across the surface so that oil is collected in a bag 7 which forms an extension rearwards of the boom along its whole length. Oil enters the bag through a gap between water-filled tube 5 and air-filled tube 4, past a valve 14 in the form of an inflatable tube divided into sections spaced along its length. Each section is individually inflated with air from tube 3 or allowed to deflate by a two-way control valve, in response to water or oil being detected in the region immediately upstream thereof by a corresponding pair of capacitance sensing wires 17, 18. Thus the bag 7 collects mainly oil. The ends of the boom are connected to manned tugs, small enough to be dropped, with the boom in a folded deflated state, from an aircraft. Streamers 22 dangling from fabric 6, which encloses the various tubes of the boom, assist coalescing of the oil globules collected. The two-way control valve comprises two valve discs (25, 26) mounted at opposite ends of a centrally pivotted lever to close either of two flow passages (Fig. 8), depending whether a solenoid coil around one passage in energised or not. The discs are mild steel washers encapsulated, with the lever, in rubber. A flat enclosing housing defines flow paths between the two passages (29, 30) controlled by the valve discs and a common passage (31) leading to a section of the inflatable tube 14. <IMAGE>

Title: Method of producing fibre or film
Inventor: BRUNSKILL WILLIAM
IPC: C08J5/18
Filed: 1992-08-19
Abstract: A water-absorbent water-insoluble fibre or film is produced by extruding an aqueous solution of a water-soluble polymer into a gaseous medium to form fibre or film. The extruded fibre or film is collected at a moisture content of 8 to 25% based on the dry weight of the fibre or film and is further dried at a temperature no greater than 100 DEG C before crosslinking the fibre or film at a temperature in the range 125 to 250 DEG C to a degree sufficient that the crosslinked fibre or film is water-insoluble. The fibre or film entering the crosslinking step has a moisture content which is reduced, preferably by at least 5%, and which is in the range 0 to 10%. The heat-crosslinked fibre is preferably treated with moist air after crosslinking to raise the moisture content of the fibre to at least 10%, particularly if the fibre is for textile processing. Water-absorbent water-insoluble coatings can be produced by a similar process.

Title: Hard disc head postioning drive system
Inventor: YAMAMOTO SATOSHI
IPC: G11B21/10
Filed: 1993-04-16
Abstract: The head 1 of a disc data store is driven to a target position by energising the motor 2 to produce a first, acceleration phase, a second, constant speed phase and a third, deceleration phase. During the constant speed phase, the speed is monitored to determine whether it is within a predetermined range of speeds. If it is, no drive current is applied to the motor.

Title: Handling frame overruns in a digital signal processing system
Inventor: ANDERSON ERIC C
IPC: G06F9/48
Filed: 1993-07-28
Abstract: In a computer system having a digital signal processor for processing a number of tasks within a frame, a method for handling a frame overrun wherein the tasks can not be processed within the frame. First, the frame overrun is detected. Next, each of the tasks are compared with a processing time which had been allocated to it. A determination is made as to which of these tasks had exceeded its allotted processing time by the greatest amount. The worst case client is notified that its task has caused an overrun. All other non-system task clients are notified that a overrun has occurred. All but system support tasks are inactivated, and processing continues. Each client must determine the correct action to take, including restarting the tasks where they left off, restarting from the beginning, or quitting. Methods for handling more serious overruns are also described. <IMAGE>

Title: Cable or hose protector
Inventor: NORBURY STEPHEN JOHN
IPC: F16L7/00
Filed: 1994-04-22
Abstract: A cables or hose protector comprises an outer tube 5 which can hold, centrally spaced within, a cable or hose 1 or a smaller diameter. The device can be held at either end with holding means provided 2 and extended or compressed along the length of the cable or hose, and held in either state on the cable or hose with releasable securing devices 8 in both ends. As the device is of a larger diameter than the cable or hose it will be more visible and will shield the cable or hose. The manufacture of the device predominantly from coloured material which would make it colour visible in its use environment would be a benefit. Means to stop flow through the cable or hose may be provided. The extendibility and compressibility would allow space saving storage of the device. <IMAGE>

Vibration sensor (5) triggers the alarm to emit a sound whenever abnormal vibration is detected. The circuit 4 has a power supply that is securely protected by the outer padlock case 15 to prevent damage and power loss. The key head 11 of the padlock mechanism has a two-position rotating lock setting that can be selectively locked or unlocked with or without setting the circuit so as to prevent the unwanted sounding of the alarm. <IMAGE>
